To all whom it may concern.

Be it known that I, JAMES E. FERGUSON, a citizen of the United States,residing at Dwight, in the county of Livingston and State of Illinois,have invented a new and useful Lubricant-Dispenser, of which thefollowing is a specification.

he present invention relates to improvements in a lubricant dispenser,one object of the invention being the provision of a novel and improveddispensing machine adapted to be used in garages. or elsewhere for usein dispensing heavy oils, such as grease, and other liquid orsemi-liquid substances.

Another object of the invention being the provision of a novelmechanism, wherein a main supply has means simultaneously operated todeliver into a dispensing chamber, a predetermined quantity oflubricant, said dispensing chamber being with means for projecting thelubr cant thereupon as dispensed and for simultaneously cutting offcommunication between the chamber and the main supply tank.

A further object of the present invention, is the provision of a deviceof this character which may be easily operated without soiling theclothes and hands of the operator and which by the simple manipulationof a crank connected to a single shaft will operate mechanisms forremoving a predetermined amount of lubricant from the main supply tankto a dispensing chamber and for removing the same lubricant from suchchamber as desired.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the detzfils of construction hereinafterdescribedand claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

ln the drawings, Figure 1 is a view partly in elevation and partly insection ofthe complete mechanism, the respective pistons of the maintank and the dispensmgchamber being in intermediate position. Fig. 2 1sa top plan view of the complete mechanism.

*ig. 3 the lower ing the dispensing chamber. plan view of the dispensingis an enlarged detail sectional view of portion of the supply tank show-Fig. 4 is a top chamber showfurther provided ing a portion of the tankin section and the feed screw for the plunger of the dispensing chamberin section. Fig. 5 is a section taken on line 5'5 of Fig. 3. Fig. 6 is asection taken on line 66 of Fig. 3.

Referring to the drawings, the numeral 1 designates the cylindricalwalls of a main dispensing or supplying chamber or tank, which isprovided with the removable disk bottom 2, with the center bearingopening 3 for the feed screw 4, said feed screw 4 is of substantiallythe same length as the cylindrical portion of the tank and is providedat its upper end with the squared portion 7, while mounted intermediateupon the screw for movement up and down as the screw is rotated, is thedisk plunger 5, which is proarms 6, which constitute a: means forengaging the lubricant within the tank to hold the disk against rotatingduring the longitudinal movement thereof upon the screw. It is alsoapparent that the disk 5 may be held against rotation by other means asfor instance as a spline connected to the periphery thereof in theinterior of the tank '1. but it has been found in practice that theradial arms 6 are all that is necessary inasmuch as the lubricant isusually a stiff grease and therefore offers sufiicient resistance tomaintain the disk 5 against rotation.

The upper end 7 of the feed screw 4 is adapted to fit Within the squaredsocket 8 of the short or stub shaft 9,which is rotatably mounted in theremovable cover or disk 10 of the tank'l. This cover 10 is adapted to beheld in place by means of the arm 11 which is connected to the uppersurface of the cover and the hook 12. This renders it necessary toslightly oscillate the cover 10 so as to disengage the arm 11 from thehook 12 when it is desired to remove the cover 10 and fill the tankaswill later ap pear. A large bevel gear 13 is carried by the shaft 9 andconsequently by the cover 10, while also carried by the cover 10 to oneside thereof is the bracket 14, which is provided with the pivotedmember 15 which is normally held in encircling relation by means of thethumb screw 16, so that the short section 17 of the shaft may beproperly journaled therein with the parts in the position as shown inFigs. 1 and 2, or whereby the member 15 may be thrown backwardly topermit the shaft'17 to be elevated upon its hinge joint 19 so as toplace the gear 18 out of mesh with the gear 13 and such position. Atthis time, the port 30 thus perm't the removal of the cover 10 to hasbeen moved from registration with the have access to the tank 1. port 28to registration with the ports 27 The other section 20 of the driveshaft is and 26 and the plunger 36 is in its lowerjournaled upon thebracket 14 so that the most position, having expelled the lubricant 0brackets 14 and 14' constitute a support within the shell 30 through theports 30', for'the shaft consisting of the sections 17 28 and throughthe dispensing pipe 29 to and 20. Clutch members 21 and 22 are caranydesired place. ried by the shaft sections and the spring There isconnected to the upper end of the .23 normally holds the clutch memberstofeed screw 34, a sleeve 43, which Is further 75 gether, so: that whenthe crank 24 is rotated provided with the rectangular bore 44 forcounter clockwise, the ear 18 is rotated and the sliding reception ofthe rectangular stem consequently the fee screw 4, the same 45 of theshaft 46, said shaft 46 being ourbeing movedto the left so that theplunger naled in the support 14' and carrying the 5 6 is moveddownwardly and the plunger 36, gear 47 which is in mesh at all timeswith 80 as will presently appear is moved upwardly. the gear 48 fixedupon the shaft 20. Thus When thecrank 24 is moved in the opposite 1tWlll be seen that when the crank 24 1s direction, the clutch members 21and 22 do moved 1n either direction, the gear 48 will not engageand therf r th screw 4 r transmit motion to the ear 47 and conse- 'i t ti arywh'l th rew 34 a d its quently rotate the sha t 46, the tubular 85piston 36 as'will later appear is rotated to m m er 43 and the feedscrew 34. move downwardly. 1 \Vhen it is desired to fill the tank 1 withConnected to one side ofthe tank 1 near the lubricant, the thumb screw16 is operth b tt m th fi th yli dri al mated to release the hihgingmember 15 so 25 h 25, hi h e titutes the dispensing hat the shaftsection 17 carrying the gear 90 member of the present apparatus. There18 may be swung upwardly and away from is provided in one wall thereof,an inlet the upper end of the tank 1 and out of ent, 26, which i l d i rgistr ti n with gagement with the gear 13. The cover 10 IS the. outletport 27 of the tank 1 so that then rotated to release the arm 11 fromthe 30 lubricant within the tank 1 may be fed hook 12, at which time,the cover maybe re- 95 within the dispensing member through the moved.The feed screw 4 is now removed ports 27- and 26, there being disposedto carryingwith it the plunger 6. The plunger aline the member 25, anoscillatory shell 30, 6 18 then removed from the feed screw and which isrovided with the port 30 disposed the feed screw replaced with its lowerend to be placed into and out of registration within the socket 3, atwhich time the lubriog with the respective ports 27 and 26 and 28. cantmay be placed within the tank 1. After The upper end of the shell 30 isconnected the tank has been filled with the lubricant, by means of thescrew 31 to the disk 32. the plunger 6 1S placed upon the feed screwThis disk 32 is provided with the threaded 4 and the cover 10 is placedin position in 0 opening for the reception of the feed screw the upperend, the arm 11 being rotated to 105 34, whose lower, end is connectedby means engage the hook 12. The shaft section 17 is of the yoke 35 tothe piston 36. Thus the now lowered so that the gear 18 is placed indisk 32 andthe shell 30. are connected for mesh with the gear 13 and thehinge mem-' movement together and in order to impart ber 15 is lockeddownwardly by means of 5 movement to the piston 36 as the feed screw thethumb screw 16. Thus the parts are 11 34 is rotated, such disk 32 mustbe 'mainnow in position for operation. tained in a stationary position.This 'is ac- Assuming that the plunger 6 is at the top complished bymeans of the spring actuated and therefore the plunger 36 is at thebotpawl 38 adapted to seat Within the recess 37 tom of the shell 30, theports 27, 26 and 30 formed in the under side of the cover 36 being inregistration, the handle 22 is opcr- 11 of the member 25, such lockingmember 37 ated counter clockwise and thus imparts robeing so disposed asto pro ect slightly tation through the gears 18 and 13 to the within theperiphery of. the opening 39 0 feed screw 4 and consequently moves thethe cover 36 so as to be engaged by the disk disk 6 downwardly tocompress the lubri- 40 carried at the upper end of the feed cantwithinthe tank and force that at the 15 screw 34 in its downward movement.Thus bottom through the ports 27, 26 and 30' into when the plunger 36 ismoved to its farthe lower end of the shell 30. Simultathest movement,the disk 40 will engage the neously with this action, the gears 48 and47 locking member 38 and release the same rotate the' feed screw 34 soas to elevate the from the recess 37 so that the disk 32 and plunger 36.The threads upon the feed 1 the shell 30 will be rotated with the feedscrews 4 and 34 are so regulated that the screw 34 so as to cause thepin 42 to ride disk 6 moves longitudinally within the tank in thearcuate slot 41 formed in the cover 1 a sufficient distance only tocause a sufii- 36' and finally to engage the spring clip cient quantityof lubricant to be ejected into 43 which holds and receives the pin 42in the shell 30 to fill the same, while the plun 1 ger 36 is moved fromthe extreme lower end of the shell to the upper end thereof. As theplunger 36 approaches the disk 32, the pin 42 having been seated withinthe spring clip 43, and therefore held against rotation, the frictionalrotation of the plunger 36 at the under side of the disk 32 and thecontinued rotation of the screw 34 will cause the disk to be rotated inthe opposite direction or until the pin 42 assumes the position as shownin Fig. 4, at which time the spring actuated lock 38 will snap in therecess 37 and thus lock the disk 32 and the shell 30 in such position.The shell during this rotation is moved to cause the port 30 to beplaced from registration with the ports 27 and 26 into registration withthe port 28 so that communication is shut off from the tank 1.

When it desired to dispense the lubricant from the member 25 through thepipe 29, the crank 24 is operated clockwise at which time, the clutchmembers '21 and 22 remain inoperative and therefore the screw 4 is notoperated. The shaft 46 then operates the screw 34 to cause the plunger36 to be moved downwardly. Thus as the plunger 36 is moved downwardly,the lubricant is ejected through the ports 30 and 28 into the pipe 29.As the plunger 36 approaches the lower end of the member 25, the disk 40is brought within the recess 39 of the cover 36 and engages the springactuated lock 38 to release tliesame from its recess 37 so that thecontinued rotation of the screw 34 will produce sufficient friction uponthe threaded portion 33 of the disk 32 to rotate such disk so that thepin 42 is moved from the position as shown in Fig. 4 to engage thespring clip 43, or at the extreme end of the arcuate slot 44. At thattime, the shell 30 is rotated so as to place-the port 30' out ofregistration with the port 28 and into registration with the ports 2'1and 26.
